Description

[0001] The invention relates to a post-and-beam construction for facade renovation, as well as a post and a beam for producing the post-and-beam construction.

[0002] When renovating facades, particularly in the area of ​​historic preservation, high demands are placed on the precise restoration of the original appearance of the facade while simultaneously implementing modern requirements for energy savings and structural integrity.

[0003] The invention is based on the objective of providing a post and a beam for the production of a post-beam construction, as well as a post-beam construction with which these requirements can be met.

[0004] This task is solved, according to one aspect, by a post-and-beam construction for facade renovation, in which the posts and beams are each designed as composite profiles and screwed together. The post-and-beam composite profile has a central section and at least two hollow chambers arranged symmetrically to the central section for receiving screws. The beam-and-beam composite profile has corresponding openings for screws. Thus, the posts are designed as post-and-beam composite profiles, and the beams as beam-and-beam composite profiles. The hollow chambers of the post-and-beam composite profile project laterally from the profile, extending away from it in opposite directions. Therefore, the hollow chambers act like cross-sectional extensions of the central section.

[0005] In its intended use, the post-and-beam construction consists of at least one post arranged vertically and at least one beam arranged horizontally. Typically, a number of posts are arranged vertically and a number of beams horizontally, forming a grid-like post-and-beam structure, with each pair of adjacent posts and two adjacent beams defining a space. Facade elements can be inserted into or attached to the post-and-beam structure, either within these spaces or covering them on one of its exterior surfaces. At the intersections between beams and posts, the beams are screwed to the posts. At least one beam is screwed to a hollow chamber of at least one post.The screws used to connect posts and rails extend through the rail and through a wall around the post that defines the hollow chambers, so that the screw terminates within the hollow chamber. The invention is based on the understanding that using a composite profile for posts and rails offers static advantages, allowing for thinner walls and eliminating the need for a core. This results in additional benefits regarding manufacturing and assembly times, as well as material savings. Furthermore, screwing the rail and post together allows for faster manufacturing and assembly than, for example, T-connectors. In particular, the use of composite profiles allows for the precise reproduction of existing construction profile contours due to their manufacturing flexibility.In particular, the hollow chambers of the post composite profile allow for the screw connection of posts and rails, thus maintaining the existing dimensions and appearance while using resource-saving screw connections.

[0006] According to a second aspect, the task is solved by a post. The post has a central section and two hollow chambers arranged symmetrically to each other on two opposite sides of the central section, extending in opposite directions from the central section. The hollow chambers serve as receptacles for screws. The post is designed as a composite post profile and has a structural post profile on which the hollow chambers are arranged. The hollow chambers have receptacles for seals. The post also has a facade-side post profile, whereby the structural post profile and the facade-side post profile have mutually facing and spaced-apart outer surfaces in intended use.Each of the outer surfaces has at least one insulating recess for creating a positive connection with corresponding extensions of a connecting element, and the facade-side post profile has at least one bore for connecting a pressure strip to the facade-side post profile.

[0007] The connecting element can serve as a form-fitting connection to both the structural post profile and the facade-side post profile. In particular, the connecting profile acts as insulation and therefore has a lower thermal conductivity than both the structural post profile and the facade-side post profile.

[0008] According to a third aspect, the task is solved by a transom. The transom is designed as a composite transom profile with a structural transom profile and a facade transom profile. The structural transom profile is essentially T-shaped, with a flange and a web extending transversely to the flange, which has at least one insulating receptacle for creating a positive-locking connection with corresponding extensions of a connecting element. The flange has at least one through-hole for screws and at least two receptacles for seals. The facade transom profile has at least one bore for connecting a pressure strip to the facade transom profile, as well as at least one insulating receptacle for creating a positive-locking connection with corresponding extensions of a connecting element.The insulating mounts of the structural-side beam profile and the facade-side beam profile are arranged on mutually facing and spaced-apart outer surfaces in the intended use.

[0009] The connecting element can serve as a form-fit connection to both the structural-side and the facade-side transom profiles. In particular, the connecting profile acts as insulation and therefore has a lower thermal conductivity than both the structural-side and facade-side transom profiles.

[0010] Preferably, the post-composite profile has a structural post profile and a facade-side post profile, connected via at least one insulation layer and / or the transom-composite profile has a structural transom profile and a facade-side transom profile, connected via at least one insulation layer.

[0011] The structural post profile represents a component of the post located on an inside of the facade, and the facade-side post profile represents a component of the post located on an outside of the facade.

[0012] The structural-side beam profile represents a component of the beam arranged on an inside of the facade, and the facade-side mullion profile represents a component of the beam arranged on an outside of the facade.

[0013] The facade elements, arranged on the post-and-beam structure and forming the facade, are positioned such that they meet vertically at the beams and horizontally at the posts. The facade elements are offset from one another in such a way that the structural post and beam profiles and the facade-side post and beam profiles extend into the space between the facade elements. In other words, the structural post and beam profiles extend from an inner side of the facade into the space between the facade elements, and the facade-side post and beam profiles extend from an outer side of the facade into the space between the facade elements. The opposing structural post profiles and the facade-side post profiles are connected by insulation.Similarly, the load-bearing beam profiles extending towards each other and the facade-side beam profiles are connected to each other via insulation.

[0014] This design particularly addresses the requirements for energy savings and reduces heat loss through the structure. Furthermore, the composite profile construction allows for the optimal integration of modern triple glazing into the facade. Preferably, the load-bearing mullion profile and the facade-side mullion profile, and / or the load-bearing transom profile and the facade-side transom profile, each have at least one insulating receptacle to create a positive connection with corresponding extensions of insulation located at the distance between the facade elements.

[0015] This allows the profiles to be easily and securely connected to the insulation.

[0016] The hollow chambers of the post composite profile are preferably arranged in the structural post profile. In one embodiment, the structural post profile has a central section on which the hollow chambers are arranged laterally and symmetrically to each other on two opposite sides, extending from the central section in opposite directions. It is further preferred that receptacles for seals are arranged on each of the hollow chambers. The receptacles are open towards the facade element, so that a seal inserted into the receptacle is located between the receptacle and the facade element, bearing against the facade element and thus providing a seal. This is made possible, in particular, by the hollow chambers forming a cross-sectional widening of the central section, so that the hollow chambers extend beyond the facade elements on both sides of the post.

[0017] In one embodiment, the load-bearing transom profile is essentially T-shaped, with a flange and a web extending transversely from the flange. The web has at least one insulating receptacle for creating a positive-locking connection with corresponding extensions of the insulation. The flange has at least one through-hole for screws. This allows for the advantageous screw connection of the transom profile and mullion profile to be easily achieved. The facade-side transom profile is formed by a web and positively connected to the load-bearing transom profile via the insulation. For this purpose, the facade-side transom profile also has at least one insulating receptacle for creating a positive-locking connection with corresponding extensions of the insulation.

[0018] In a further embodiment, the post-and-beam construction comprises at least one pressure strip with at least one receptacle for screws, two webs arranged on opposite sides of the receptacles, each with a groove, and at least one clip strip designed as a U-profile. The clip strip has projections on its open profile side that correspond to the grooves of the webs and are designed to engage behind the grooves of the pressure strip's webs. This allows a force-fit and / or form-fit connection between the pressure strip and the clip strip to be quickly and easily established by simply "placing" the clip strip on. The pressure strip is, in particular, significantly wider than the clip strip. The facade elements are pressed against the post and beam via the at least one pressure strip and fixed by means of the screws.A clamping connection is implemented here, in which the facade elements are clamped and thus held between the structural mullion and transom profiles and the facade-side mullion and transom profiles. The clip strip covers the screws in the pressure strip. The design of the clip strip and pressure strip can also facilitate the exact replication of the dimensions and visual appearance of existing listed building structures.

[0019] It is preferred if the facade-side mullion profile and / or the facade-side transom profile have bores for receiving screws with which the pressure strips can be attached. Preferably, the clip strips are designed to be elastic enough to be clipped onto the webs for a form-fitting hold.

[0020] The clamping connection for securing the facade elements between the structural mullion and transom profiles and the facade-side mullion and transom profiles is created by first connecting the structural mullion and transom profile to the facade-side mullion and transom profile via insulation. The pressure bar is then screwed to the facade-side mullion and transom profile from the outside of the facade. The pressure bar is designed to be wide enough to brace itself against the facade elements when screwed in, and the resulting clamping force is transferred via the insulation to the structural mullion and transom profile, which is also designed to be wide enough to brace itself against the facade elements.In the case of the structural mullion profile, the laterally and symmetrically arranged hollow chambers on the central section create sufficient width to brace the structural mullion profile against the facade elements. In the case of the structural transom profile, the flange is sufficiently wide to overlap the facade profiles and brace against them. Consequently, the structural mullion and transom profiles and the facade-side mullion and transom profiles clamp the facade elements between them.

[0021] Preferably, the pressure bars have recesses for seals.

[0022] The structural and facade-side mullion and transom profiles are preferably metallic profiles, in particular aluminum profiles, and more preferably profiles comprising recycled aluminum, such as Circal. For sustainability reasons, it is particularly preferred if these profiles consist of 100% recycled aluminum. Ideally, parts of the original structure can also be melted down and reused.

[0023] Further embodiments are explained below by way of example with reference to the drawings. These show Fig. 1 a schematic detailed sectional view of a post-and-beam construction according to the invention in the area of ​​the post; Fig. 2 a schematic detailed section view of a post-and-beam construction according to the invention in the area where the post and beam meet. Fig. 3a schematic detailed section view of a post-and-beam construction according to the invention in the area of ​​the beam.

[0024] In the following description of exemplary embodiments, similar reference numerals generally refer to similar elements.

[0025] Fig. 1 Figure 1 shows an embodiment of a post-and-beam construction 1000 according to the invention for a facade renovation in which the post 100 and beam (not shown here) are each designed as a composite profile and can be screwed together. Fig. 1Figure 1 shows a cross-section through the mullion profile and two facade elements 800 arranged laterally next to the mullion profile. The mullion profile has two hollow chambers 111 arranged symmetrically to a central section 113 and laterally on two opposing outer surfaces of the central section 113, for receiving screws 600. The hollow chambers 111 extend outwards from the central section 113 in opposite directions. The transom profile, not shown here, has corresponding penetrations 201 for screws. This allows the mullion profile to be connected to the transom profile with minimal assembly effort. The mullion profile has a structural mullion profile 110 and a facade-side mullion profile 130, which extend at a distance between the two facade elements 800.The structural mullion profile 110 and the facade-side mullion profile 130 are connected by positive-locking connections to insulation 120 arranged at the distance between the facade elements 800. The insulation 120 connects the structural mullion profile 110 and the facade-side mullion profile 130 to each other. Furthermore, the structural mullion profile 110 and the facade-side mullion profile 130 each have an insulation receptacle 114, 132 for creating a positive-locking connection with corresponding extensions of the insulation 120 arranged at the distance.

[0026] The structural post profile 110 here has a central section 113 on which hollow chambers 111 are arranged symmetrically to each other and laterally on two opposing outer surfaces of the central section 113. The hollow chambers 111 each have at least one receptacle 112 for seals.

[0027] The central section 113 of the structural post profile 110 is narrower than the gap between the facade elements, so that the central section 113 extends partially into the gap. The hollow chambers 111 of the structural post profile 110 cover the facade elements 800. The facade-side post profile 130 is located entirely on one outer side of the facade at the gap between the two facade elements 800.

[0028] The post-and-beam construction 1000 further comprises at least one pressure strip 300. The pressure strip 300 has at least one receptacle 320 for screws 700. In addition, the pressure strip 300 has two webs 310 arranged on opposite sides of the at least one receptacle, each with a groove 311. The post-and-beam construction also has at least one clip strip 400 designed as a U-profile, which has projections 410 on its open profile side corresponding to the grooves 311 of the webs 310 of the at least one pressure strip 300, and which are designed to engage behind the grooves 311. The at least one pressure strip 300 is in particular significantly wider than the at least one clip strip 400. The facade-side post profile 130 has at least one bore 131 for receiving screws 500, with which the at least one pressure strip 300 can be attached to the facade-side post composite profile 130.In the illustrated embodiment, the at least one clip strip 400 is designed to be elastic such that it can be clipped onto the webs 310 for a form-fitting hold on the at least one pressure strip 300. The at least one pressure strip 300 has at least two receptacles 330 for seals 700. The receptacles 330 are open in the direction of the facade elements 800, so that a seal arranged in the receptacle 330 is located between the pressure strip 300 and a facade element 800 and, in particular, bears against the facade element 800, thus creating a sealing effect.

[0029] The facade elements 800 are pressed between the mullions 100 and the transoms 200 via at least one pressure strip 300 and fixed by means of screws. This creates a clamping connection. The at least one clip strip 400 covers the screws on the at least one pressure strip 300.

[0030] The clamping connection is created as described below: On an inner side of the facade formed by the facade elements 800, the structural mullion profile 110 is arranged such that the central section 113 extends into the space between the two facade elements 800. The two hollow chambers 111, arranged symmetrically to each other and laterally on the central section 113, extend away from the central section 113 and beyond the facade elements 800, so that the structural mullion profile 110 with the hollow chambers 111 abuts the two facade elements 800. The central section 113 extends partially into the space between the facade elements 800 and is positively connected to the insulation 120 arranged in this space. On an outer side, the facade-side mullion profile 130 is arranged in the space between the facade elements 800 and is also positively connected to the insulation 120.On the outside, the pressure strip 300 is connected to the facade-side mullion profile 130 via a screw connection. The pressure strip 300 is designed to be wide enough to cover the facade elements 800 and brace itself against them. The pressure strip 300 thus essentially acts as a widening of the facade-side mullion composite profile 130, enabling the facade-side mullion profile 130 to effectively brace itself against the facade elements 800. The screw connection creates a clamping force which, via the positive-locking connection with the insulation, is transferred from the outside through the gap to the inside of the facade onto the structural mullion profile 110, so that the facade elements 800 are consequently clamped between the hollow chambers 111 of the structural mullion profile 110 and the pressure strip 300.

[0031] In Fig. 2The post-and-beam construction 1000 is shown schematically in the area where post 100 and beam 200 meet. Fig. 2 Figure 1 shows a cross-section through a post at the connection point with a transom, i.e., viewed vertically between two facade elements 800. The transoms 200 each have flanges 211 and through-holes 201 for the screws 600, with which the transoms 200 are fastened to the post 100 at the hollow chambers 111. The screws 600 are concealed within the hollow chambers 111 of the post 100.

[0032] Fig. 3 Figure 1 shows a schematic detailed sectional view of a post-and-beam construction 1000 according to the invention in the area of ​​the beam 200. The beam 200 is designed as a composite beam profile and comprises a structural beam profile 210 and a facade-side beam profile 230, connected via insulation 220. Fig. 3shows a cross-section through the composite beam profile with two laterally arranged facade elements 800.

[0033] The structural-side transom profile 210 is located on an inner side of the facade formed by the facade elements 800. The facade-side transom profile 230 is located on an outer side of the facade. Extending from the inner side, the structural-side transom profile 210 extends into a gap formed between the two facade elements 800. Extending from the outer side, the facade-side transom profile 230 extends into this gap. Insulation 220 is installed within this gap and is positively connected to both the structural-side transom profile 210 and the facade-side transom profile 230.

[0034] For this purpose, both the structural-side beam profile 210 and the facade-side beam profile 230 have at least one insulating receptacle 214, 232 for creating a positive-locking connection with corresponding extensions 121, 221 of the insulation 220 arranged at the distance. The structural-side beam profile 210 is essentially T-shaped here, with a flange 211 and a web 212 extending transversely from the flange 211, wherein the web 212 extends into the space between the two facade elements 800 and the flange 211 extends beyond the facade elements 800 on the inside of the facade and is supported against the facade elements 800.

[0035] The web 212 of the structural beam profile 210 has an insulating receptacle 214 for positive connection with the insulation 220 arranged at the distance and the flange 211 has openings for screws (not shown here).

[0036] The facade-side transom profile 230 is arranged on the outside of the facade at the distance between the facade elements 800 and has at least one bore 231 for receiving screws 500. The facade-side transom profile 230 can be connected to a pressure bar 300 via this bore. The pressure bar 300 ensures that the facade elements 800 are clamped between the pressure bar 300 on the outside of the facade and between the structural-side transom profile 210 on the inside of the facade, and for this purpose has at least one receptacle 320 for screws 500.

[0037] The screws 500 are covered by at least one clip strip 400 designed as a U-profile. For this purpose, the pressure strip 300 has two webs 310 arranged on opposite sides of the receptacles 320, each with a groove 311. The clip strip 400 has projections 410 on its open profile side corresponding to the grooves 311 of the webs 310 of the at least one pressure strip 300, which are designed to engage behind the grooves 311. Preferably, the at least one clip strip 400 is designed to be elastic such that it can be clipped onto the webs (310) to create a positive and / or force-fit connection. Reference symbol list
